Marine Carbohydrate-Based Compounds with Medicinal Properties

<p>The marine environment is considered one of the most important sources of natural bioactive compounds with extremely rich biodiversity. Marine glycans are remarkable molecules playing a determinant role in biological processes. Marine ?arbohydrate-containing substances have drawn increasing attention in the ?eld of biomedicine for their various biological activities such as antitumor antivirus hypoglycemic immunomodulatory and anticoagulant. These compounds obtained from marine sources such as algae microbes and animals are usually biodegradable and biocompatible and exhibit biological properties that contribute to the discovery of a wide range of new bioactive substances with special pharmacological properties of interest to medicine. Carbohydrate-based compounds include glycans glycoproteins proteoglycans glycolipids and low-molecular and complex glycosides of differential origin. Many of the polysaccharides allow for loading lower drug dosages which may lead to a drastic reduction of the side effects caused by the drugs. In addition the structure of polysaccharides can be relatively easily modi?ed in order to synthesize derivatives with desirable characteristics for drug delivery. Complexes on the basis of carbohydrates are often prepared to improve their functional properties. In this Special Issue we seek to contribute to the discussion of various aspects of marine carbohydrate-containing compounds and provide a unique platform for a new concept for their use in medicine in order to continue to facilitate further research in this area.</p>
